How many days does it take to mine a bitcoin in a graphics card?

Production is decreasing every year, and then according to the computing power, this is not fixed. Personally, I feel that mining coins is not as good as tun coins, and I have made 30% of my money in a wave of Chinese currency hoarding this year.

Because compared to the complex computing of the CPU, the GPU used by the graphics card performs general-purpose computing. Therefore, hundreds of stream processors can be stacked, each stream processor is like a small CPU, although its ability to run complex programs is far less powerful than the CPU, but it can't support more stream processors, so the actual performance, especially the single-precision floating-point performance, is much stronger than the CPU.

Mining including Bitcoin can be considered to be using the graphics card to do continuous general computing, and the complexity of this calculation is relatively low and quite repetitive, and the stream processor used by the graphics card is just suitable for such an algorithm.

It's like constantly solving a system of equations, the graphics card is 2000 middle school students, and the CPU is 8 math doctors. Although the mathematical knowledge of a Ph.D. in mathematics far exceeds that of middle school students, the speed of solving a medium system of equations like virtual currencies is certainly not as fast as that of 2,000 middle school students.

1. "Mining" of graphics cards is actually a visual statement for the production process of "Bitcoin".

2. In essence, it is the process of CPU, GPU and other processors to obtain Bitcoin through calculation, and because the advantage of GPU is much greater than that of CPU in related calculations, everyone basically uses graphics cards to focus on mining, which also forms the term "graphics card mining".

Mining bitcoin mainly uses a lot of calculations, and the running power of high-end graphics cards is obviously much stronger than that of CPUs. So mining bitcoin with a high-end graphics card does not use a cpu. Mining with a graphics card is obviously efficient and fast.

Because the parallel processing power of the graphics card is relatively strong.

The CPU is a few commanders, the GPU is a lot of soldiers, do you use commanders or soldiers for mining?

First of all, Bitcoin was mined with CPU at the beginning, but the number of CPU cores was small, and the mining algorithm was a simple but complicated algorithm, which did not require a strong core, and required a large number of small cores to be calculated at the same time, so the method of graphics card mining was developed. Now, later, a professional mining machine has been developed, which only has a computing function, no display function, and has a large computing power and high efficiency. At present, no one uses graphics cards to mine bitcoins, they are all professional mining machines.

Graphics cards are basically mining Ethereum. However, at present, there are also Ethereum mining machines on the market one after another, the computing power of the whole network has skyrocketed, and Ethereum has also been put on the agenda, and I believe that the price of graphics cards will be reduced in the future.

The internal structure of the CPU and the GPU is quite different, the CPU uses a small number of but more powerful ALUs (arithmetic operation units), while the GPU uses a large number of ALUs with a simpler structure, so the performance characteristics of the CPU and the GPU are also completely different: the CPU focuses on complex logic control and general-purpose serial operations, while the GPU is biased towards handling large-scale concurrent computation (graphics and image processing, which also belong to this kind of operation), So the CPU and GPU belong to their own roles.

Mining bitcoin does not require a high single computing power, the number of cores required, and the number of GPU cores is large, so a graphics card is required.

Little pot friend, have you ever heard of GPU?

Isn't this kind of question supposed to go?

It's too late to mine bitcoin now, so I advise you not to invest manpower and material resources. Now the cost of mining is higher than the output.

Hello; This computing power is not good, it mainly depends on luck.

Ordinary people dig... The feasibility is 0%,It's okay to ridicule the graphics card.,As a profession, you first have to have a lot of capital.。。。

PC mining, 1 graphics card is too little, you need more than one graphics card, such as one, you can't afford the electricity bill, this pile of things (even if you only have 4 graphics cards, every day full load is also an electric tiger), when digging, the money is fully loaded, heat dissipation, power supply is not guaranteed, you hang these things early. Remember someone's room because these graphics cards turned into a dryer.。。 Drying clothes and hanging in the room dries faster, which shows the great heat, and if the heat dissipation is not good, it will also cause various problems.

In one, the price of mining with a graphics card is high, a top-of-the-line graphics card... **It's not expensive, it's distressing to buy a few pieces (except for local tyrants), the whole computer has a large investment, of course, whether you will dig it is still a problem.

Therefore, it is not recommended for ordinary people to mine, it really can't hurt.

Now it's too late for you to enter the industry, I'm afraid you won't be able to mine a single bitcoin in a month, and you can go and search the news on the Internet, 1% of the world's people control about 80% of the world's bitcoins.

Now the mining efficiency is already very low, if you use ordinary PC mining, let the graphics card uninterrupted all-weather full load computing, will lose the life of the graphics card, if the platform heat dissipation is poor, it is easier to hang, and you can't afford another electricity bill.

It is advisable to use a dedicated mining rig to mine Bitcoin.

You can't dig in vain and waste electricity, and mining is super hurtful, and the graphics card doesn't believe you try!

Generally speaking, AMD's graphics cards are more suitable for mining graphics cards due to the architecture and ** factors!

HD7990 is the current king, and it is said that the electricity cost for mining each bitcoin with it is 130 140 yuan, which means that a monster card like him also needs to work for about 20 days to get a bitcoin. One bitcoin may consume 300 watts of electricity, not counting the wear and tear of a computer.

The hardware of the mining platform other than the graphics card also consumes electricity, and the CPU motherboard, memory, hard disk, including the power supply that supplies the whole machine also require electricity because there is no 100% conversion rate. In contrast to monitors that can be turned off in pure standby, they have to intervene.

The faster the graphics card is mined, the less unnecessary power consumption is consumed per 1 bitcoin acquired, in which case the faster the graphics card tends to have an advantage. If you set up a multi-card platform, the net profit per unit of time can be higher.

The lower the performance of the card, the more power it consumes on average!

In a word! Be cautious when investing.

Now the use of graphics cards for mining has lagged behind, and special mining machines are used. The more streams the graphics card, the better, so AMD's is better.

Wake up, it's not suitable now, unless you are a local tyrant and buy a "butterfly" to dig directly, otherwise the electricity bill will not be enough!

7970 of this kind However, it has been calculated that 7850 is the most profitable.

Upstairs made a mistake, Bitcoin came out in 2009, how can Bitcoin mining machines be years old!

Now, of course, there are still people mining, there are about 21 million bitcoins in total, and there are currently about 13 million in the world, and there are still 8 million that have not been calculated. However, now the mining is basically a large-scale integrated mining machine, and the era of graphics card mining ended at the end of last year, because with more and more bitcoins being mined, the mining difficulty is automatically increasing, and large-scale mining equipment is manufactured in batches, resulting in the computing power of the graphics card can no longer produce positive returns.

For example, the current mining difficulty is 16,818,461,371, and the hashrate of a good graphics card such as ATI5970 is 800mhash s, and it takes 2863 years to mine a bitcoin. The hashrate of large integrated mining rigs can reach 2thash s, and it will take more than 1 year to mine a bitcoin. There are already many manufacturers around the world producing such large-scale mining machines, and the computing power is still improving, and there are more than 100,000 units of this equipment currently in use.

Speaking of which, it has been 7-8 years since the advent of mining machines, unless you invest a lot of money, if you play casually, you will lose money.
